Etymology: "Disputant" is a plain formation: English "dispute" with the suffix "-ant," which marks someone who performs an action. The base "dispute" came into Middle English from Old French "desputer," itself from Latin "disputare," meaning to weigh up or argue a matter back and forth. That Latin verb was built from "dis-," meaning apart or in different directions, and "putare," to reckon or think, so the original sense was closer to sorting out an account than to shouting over one. The suffix does the rest. Its ancestor, Latin "-ant-," was attached to verb stems to name the doer of an action, and it passed through Old French "-ant" into English. English therefore has "disputant" alongside similar agent nouns such as "combatant" and "participant," all built on the same pattern of verb stem plus "-ant."
